Catheter closure of secundum atrial septal defects.
Catheter occlusion of atrial septal defects has its roots in the 1950s, with early devices being implanted during closed-heart surgery without cardiopulmonary bypass. For the past 20 years, various catheter-delivered devices have undergone testing and refinement. Designs have included single- and double-disk prostheses, with a variety of materials, delivery systems, and techniques. In this monograph, the history of atrial septal defect occluders and their evaluation, results, and prognoses will be outlined. The early work of King and Mills has been advanced in the forms of the Rashkind and Lock-USCI Clamshell occluders (USCI; Billerica, Mass), the "buttoned" device (custom made by E.B. Sideris), the Babic atrial septal defect occlusion system (Osypka, GmbH; Grenzach-Wyhlen, Germany), the Das-Angel Wings atrial septal defect occlusion device (Microvena Corporation; White Bear Lake, Minn), and others. The future holds promise for approved devices in the treatment of selected secundum atrial septal defects.
